WebThe TRH stimulates the anterior pituitary to produce thyroid-stimulating hormone (TSH). The TSH, in turn, stimulates the thyroid to produce thyroid hormone until levels in the blood return to normal.

WebMar 27, 2024 · Secondary hyperthyroidism may be attributed to an over-stimulation of the thyroid. This may be due to increased production of TSH from the pituitary gland or TSH-secreting tumor, or more rarely from overproduction of TRH from the hypothalamus or thyrotropin-releasing hormone (TRH)-secreting tumor. WebIncreased TSH, in turn, stimulates the thyroid gland to produce and release more thyroid hormones (TH). The presence of a thyrotrope cell derived pituitary tumor would therefore lead to an increase in TRH, which would then cause an increase in TSH and an increase in thyroid hormones (TH). This is the most likely scenario, as indicated by option A.
